Hi Team
we have one cisco 871 and five cisco 851 routers , all those routers are connected to each other using site to site VPN tunnels, so each router have 5 tunnels, we are usong thhese routers for IP phones, each location have 2-3 IP phones and 2-3 computers, all routers are connected to internet using ADSL modems,
out of these 6 locations 2 cisco 851 routers are getting frozen once or twice a day, and we need to reboot them, I already changed the router at one location with new one but problem is still there, but if i look for the logging ( Show logging ) its shows only interface up and down status that because of reboot, i cant find what is the reason
these cisco 851 routers have 4 port LAN swithc in built, that still works even router is frozen, i was not able to ping or access the router not even using console.
Any one have any idea will be really appericaited

Could be an IOS bug.

Update IOS.
Note for ADSL, you should use 8x7 router for best results.
